I attached a sound to an emoticon "A", let's say "sound.wav". When I restarted aMSN I noticed emoticon "B" and "C" had the same "sound.wav" attached, but I just set a sound for emoticon "A". If I uncheck the box "Play a sound" from all emoticons affected, the sound is still there after a restart (box is checked). I was forced to uncheck "Play sound for certain emoticons" from preferences. I'm using svn right now, but this bug was there since 0.97.
